iphone mapview current location

I'm able to show current location on mapview. It shows round blue color circle. When I click o开发者_如何学Pythonn the circle, it shows "Current Location". I want to show users current location as green pin. on click of pin, i want to show "My Location" annotation. How to do it. Please suggest me how to do it.

Doing so is a bad idea. The blue dot and associated animation is a convention that is adhered to by all MapKit apps. Your user might be moving too. A pin is associated with a fixed location. Someone holding a phone is not a fixed point.

Please really think about the MapKit standards and Apple HIG they are there to help your users understand and enjoy your app.
